Hello, experts
I found that you have selected 40% for the L ripple parameter of the boost inductor on the UCD3138PFCEVM-026 evaluation board. In the current continuous mode, the 40% inductor current ripple is very large, but the test results of the evaluation board show that the input The ripple on the current is not very obvious. Is it the effect of the EMI filter in the circuit? Is it the EMI filter that makes the originally wider sinusoidal current ripple into a narrower input current waveform? Do you have any reference for the EMI filter design in this evaluation board?
